Method of fabricating randomly-colorized glass vessels

Abstract

A method of fabricating a randomly-colorized glass vessel includes gathering an initial gob of molten primary glass. A quantity of secondary-glass particles is introduced into the initial gob in order to form a particle-containing gob. The secondary-glass particles are made from a secondary glass that contrasts in color with the primary glass. The particle-containing gob is then heated sufficiently to melt the secondary-glass particles and create flows of the secondary glass within the primary glass. Once the desired flows have been created, the gob of primary and secondary glass is introduced into a vessel-defining mold. The mold is sealed and a quantity of gas is injected into the mold in order to form the gob of primary and secondary glass into a vessel.

1 . A method of fabricating a randomly-colorized glass vessel of predetermined shape, the method comprising:
 gathering an initial gob of molten primary glass;   introducing into the initial gob a quantity of secondary-glass particles in order to form a particle-containing gob, the secondary-glass particles being made from a secondary glass contrasting in color with the primary glass;   heating the particle-containing gob such that the secondary-glass particles melt and the molten secondary glass flows within the primary glass; and   introducing the gob of primary and secondary glass into a mold in order to form the gob of primary and secondary glass into a vessel of predetermined shape.   
     
     
         2 . The method of  claim 1  wherein the vessel is a bottle having a main body defining an internal storage cavity and a neck depending from the body, the neck being narrow relative to the main body and having an opening extending therethrough that renders the storage cavity in fluid communication with the exterior of the bottle. 
     
     
         3 . A method of fabricating a randomly-colorized glass vessel comprising the steps of:
 gathering an initial gob of molten primary glass;   introducing into the initial gob a quantity of secondary-glass particles in order to form a particle-containing gob, the secondary-glass particles being made from a secondary glass contrasting in color with the primary glass;   heating the particle-containing gob such that the secondary-glass particles melt and the secondary glass flows within the primary glass;   introducing the gob of primary and secondary glass into a mold;   injecting a quantity of gas into the mold in order to form the gob of primary and secondary glass into a vessel.   
     
     
         4 . The method of  claim 3  wherein the mold is configured to define a neck portion with a neck opening in the vessel. 
     
     
         5 . The method of  claim 4  wherein the vessel is a bottle. 
     
     
         6 . A method of fabricating a randomly-colorized glass vessel comprising the steps of:
 gathering an initial gob of molten primary glass;   introducing into the initial gob a quantity of secondary-glass particles in order to form a particle-containing gob, the secondary-glass particles being made from a secondary glass contrasting in color with the primary glass;   heating the particle-containing gob such that the secondary-glass particles melt and the secondary glass flows within the primary glass;   introducing the gob of primary and secondary glass into a pre-form mold;   injecting a quantity of gas into the pre-form mold in order to form the gob of primary and secondary glass into a pre-form vessel having at least one pre-form vessel wall defining a pre-form vessel cavity;   removing the pre-form vessel from the pre-form mold;   introducing the pre-form vessel into a finish mold; and   injecting a quantity of gas into the pre-form vessel cavity within the finish mold in order to form the pre-form vessel into a finished vessel.   
     
     
         7 . The method of  claim 6  wherein at least the finish mold is configured to define a neck portion with a neck opening in the finished vessel. 
     
     
         8 . The method of  claim 7  wherein the finished vessel is a bottle.
